Feijoas

I have two feijoa trees and every year the fruit falls off while still small and not ripe. What can I do to avoid this happening this summer. I water the trees regularly in the hotter months.

I have a feijoa tree - I am just wondering when is the best time to prune it? Or if it is better not to prune it in order to get more fruit?

How do I get bigger Feijoas? I have plenty of fruit but they are not big.

I have three seven-year-old feijoa trees that were shaded by a large walnut tree. They are quite straggly and have never had more than a couple of flowers. The walnut next door has been trimmed, but what can I now do to ensure some good fruit?

We have a 3-year-old feijoa tree and would like to transfer it to another part in our garden. Can you tell us will the tree transplant? What is the best way to do this?

We have lived at our place for about 15 years and our feijoa tree gets tiny little fruit, but they never seem to grow into anything edible. Does it need another feijoa planted with it? What type would be best?
